Hello,
I use the HRPWM of the piccolo F28069 to generate a phase shift between the pwm channels for a full bridge converter. (I introduce a phase delay in high resolution between channel 2A + 3A and 4A +5A). Now I need to change the duty cycle of all channels in high resolution, too.
I wonder if this is possible and what’s the correct setting for the CTLMODE bit?
Is there any other solution feasible? Eventually by using the CMPBHR register (see Fig. 4-4 of HRPWM). Unfortunately I cannot find further information about this topic. Now I use the CMPA register in COUNT_UPDONW mode to generate the duty cycle which is symmetric around the PRD-event.
Thanks for any information…
